Evidence / storm surfaces
How Jamestown saw the hail — from two instruments
Two instruments, one storm: NEXRAD logs the point signatures it detected overhead, while the estimated-size surface models how large the hail aloft could have grown. Agreement between them is not guaranteed — the gaps are where the model ran ahead of, or behind, the detections.
Estimated size field Radar-estimated maximum hail size across the swath, modeled from radar aloft. It reflects the biggest stone the storm could support, which may differ from what actually fell.
Only the radar-estimated size surface resolved for Aug 22, 2026 — this storm produced no NEXRAD point detections over Jamestown, so there is one map to show, not two.
The storm in context
Where Aug 22, 2026 sits in Jamestown's hail record.
This was Jamestown's 4th recorded hail day, arriving 15 days after the Aug 7, 2026 storm. By severity it ranks 2nd of the 4 storms we have logged here. Radar put the day's largest stone over Jamestown at 1.5" — radar-estimated size aloft.
The Aug 22, 2026 convective day was bigger than Jamestown: the same system put hail over 501 other tracked cities, 33 of them in Tennessee. Nearest: Alpine (6 miles west, up to 1.5"); Monroe (9 miles northwest, up to 1.5"); Livingston (12 miles west, up to 1.25").

Ground reports
What people on the ground reported
These are storm reports filed with the National Weather Service and released through the NOAA Storm Prediction Center — public-domain observations from spotters, the public, and NWS surveys. We quote each one exactly as filed.
The National Weather Service logged no spotter reports for this storm over Jamestown. That absence is ordinary — filing a report takes a person on the spot who saw the hail and phoned it in. What stands as the record for this date is the radar above, which caught the storm regardless.
High damage potential
What 1.5" hail means for Jamestown roofs.
Hail around an inch and a half is capable of cracking shingles, stripping granules, and denting gutters, vents, and siding. Risk is usually greatest near the strongest radar signal, but property-level damage still requires an on-site inspection.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$6.4M
Potential roof exposure — 533 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 3 jobs
- Illustrative work
- ~$45K
Close just 0.5% of the 533 homes in this footprint at the average $15,000 roof job. Illustrative math, not a projection — your results depend on your outreach and how the market responds.
Claim window
August 2028
Claims from this storm can typically be filed until around August 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.
Names and phones for every home in the footprint: at most $112 on top of the $150 plan.
